Radio Channel Emulators (Fading Simulators)

Keysight is the leading supplier of radio channel emulators (also called fading emulators or fading simulators) for commercial communication
standards, Over-The-Air testing of MIMO terminals and MANET applications like V2X (Car to Car and Vehicle to Infrastructure) and tactical radio communications. Keysight bought the Propsim business of
Anite in 2015.

Applications in mobile Communication

The patented radio channel emulators of Keysight can be used between real base stations (instead of base station simulators) and terminals (mobile phones, tablets, laptops) to test in real time a variety of scenarios:

Handover between different mobile communication standards

Scheduling

Diversity

Beam forming

Smart Antenna Concepts

MIMO tests over cable or Over-The-Air (OTA)

5G research

The Propsim fading simulators emulate real world radio channels which have been measured or standardized by ITU, 3GPP or CTIA. Those radio channels are characterized by

Multi-path propagation (fast fading)

Time-varying (moving) taps

Frequency shifts due to Doppler-effect

Shadowing

Antenna effects due to the movement of the terminal

All those effects can be reproduced bit by bit with a Keysight radio channel emulator.

Aerospace Option for high Speeds and long Signal Delays

With the Aerospace option for the Propsim F8 velocities up to 40000km/h and signal delays up to 1.3 seconds can be emulated.
With the Aerospace option you can define flight routes and simulate them.Aircell Success Story: Aircell has equipped more than 600 airplanes with its Inflight Connectivity Solution.
The Propsim Channel Emulation Brochure Aerospace shows how to test with Keysight's radio channel emulators:
Satellite communications, tactical data links, commercial airplane communication and in-flight-services

Propsim F32 for LTE-OTA and MANET Tests

The Propsim F32 is the radio channel emulator with the largest number of RF and fading channels.

Keysight Propsim FS8

The Propsim FS8 has the same features as the F32, in a compact table top housing, with up to 8 bidirectional RF channels and up to 32 fading
channels. Up to 6 Propsim FS8 can be synchronized. It is available in two versions, both have 40MHz RF channel bandwidth standard and 80MHz optional (with channel combining):Data sheet Keysight Propsim FS8-2.7GHzData sheet
